AUTOMATIC FILLING-REPLENISHING LOOM.

To all whom it may concern:

Be it known that I, UBALD HEBERT, a citizen of the United States, and resident of Manchester, countyof Hillsborough, State of New Hampshire, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in filling replenishing looms in which a supply of filling carriers is 'maintained in a hopper from which the filling carriers are transferred successively to the running shuttle by a suitable transferrer, and one object of the invention is to provide .means to secure the proper position of the filling carrier during transfer in order that it may be directed into the shuttle in proper position.

The invention in its more specific form relates to a filling replenishing loom of the well known Northrop type in which an intermittently rotatable hopper is employed carrying a series of filling carriers about its periphery.

More particularly the invention relates to filling replenishing looms making use of filling carriers having feeling slots in the barrel thereof such as are illustrated for example in the patents to William Parker Straw No. 906,748 granted December 15,

1908, No. 1,053,673 granted February 18, 1913, and No. 1,092,959 granted April 14, 1914. When this type of filling carrier is employed it is necessary that the slot therein shall be positioned in a definite relation to the feeler in order that the latter may work properly. Consequently the butts of the filling carriers are provided with suitable positioning means, usually slabbed or flattened surfaces generally in planes at right angles to the longitudinal planes of the slot, and these surfaces are engaged by suitable jaws Within the shuttle to retain the filling carriers in position. The filling carriers are carried in the hopper and fed therefrom by the transferrer as upon the call for filling replenishment, but when a filling carrier is forced from the hopper toward the shuttle it frequently rotates more or less and is not infrequently driven into Specification of Letters Patent.

the shuttle jaws'in improper position. As a result the feeler fails to operate or a smash is caused.

Heretofore it has been proposed as in the patent to Alonzo E. Rhoades No. 1,167,363 granted January 4, 1916 to provide a vertically movable device which shall seize the positioning faces of the filling carrier'and move down with the filling carrier maintaining it in position until it is forced into the shuttle.

The present invention provides guiding means which are fixed against vertical movement but which move rearwardly and for- 'wa-rdly and which engage with the filling carrier and prevent rotation of the filling carrier during transfer. By reason of this engagement as the filling carrier moves downwardly during transfer and thus moves downwardly with respect to the guiding means the filling carrier is held against rotation while at the same time the guiding means moves rearwardly concurrently with the lay thus enabling the filling carrier readily to be directed into the shuttle in proper position.

This invention is not limited to the particular construction illustrated and is broadly directed to a guiding means for the filling carrier during transfer wherein the filling carrier moves with respect to the guiding means while it is being guided thereby, as contra-distinguished from such a construction as shown in the aforesaid Rhoades patent where the guiding means during transfer moves downwardly with the filling carrier. In its broader features the invention therefore includes within its scope other forms devised by me and made the subject of separate applications as for example my application No. 107 ,247 filed July 3, 1916 for automatic filling replenishing looms, and my application No. 107,248 filed July 3, 1916 for automatic filling replenishing looms.

This invention in its more specific features involves a guide for the filling carrier during transfer which moves rectilinearly between the hopper and the shuttle and is given a positive movement rearwardly by being connected to the transferrer so as thus to move concurrently with the lay.

The invention further and more specifically comprises a guiding means in which the filling carrier is not only positioned rotarily but longitudinally and in its still more specific form by a yielding member engaging the rings of the filling carrier.

While this invention is disclosed herein as being applied to bobbins having feeling slots or recesses in the barrels thereof, it will be understood that it is also adapted for positioning the usual bobbins in looms and is therefore of universal adaptation to filling replenishing looms.

The nature of the invention will more fully appear from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings show so much of an ordinary automatic filling replenishing loom as is necessary to illustrate in connection therewith the improvements in mechanism which constitute one of the preferred forms of my invention.

In the drawings;

Figure 1 is a right hand side elevation and partial transverse section of a portion of an automatic filling replenishing loom of the Northrop type with the parts involved in this invention applied thereto,

Fig. 2 is a detail plan view of the guide and positioning means which constitute the novel feature of my invention showing also in cross section a portion of the link for actuating the same,

Fig. 3 is a vertical sectional view in a plane at the forward edge of the main portion of the guide.

The construction of the loom illustrated herein and to which a preferred form of the invention is applied is of the type illustrated and described at length in the patent to Stimpson and Southwick No. 823,644 granted June 19, 1906, and in view thereof and of the well known character of the Northrop loom it would be unnecessary to describe the general construction of the loom other than such parts as are immediately related to th present invention.

he loom comprises the usual breast beam 1 to which is secured a stand 2 supporting the usual rotatable hopper or battery 3 which comprises two connected disks or plates to receive, 'hold and position separate filling carriers. here filling carriers having slabbed butts are utilized, the slots 4 in the periphery of the disk 3 are of just a sufficient width to embrace the slabbed ends of the filling carriers. The plate 3 is rotatably mounted upon a shaft 5 and is connected to the opposite disk, not shown, by a sleeve 6 which is provided with recesses to receive the tips of the filling carriers.

The filling carriers or bobbins are advanced one by one into position for transfer to the shuttle by any usual ratchet mechanism such asthat illustrated in the patent to Stimpson and Southwick above referred to, which is not shown herein.

The filling replenishing mechanism comprises the usual transfer arm 7 having a hammer head 8 which preferably is cut away at 9 for purposes which will hereinafter be described, the arm 7 being a portion of the bell crank lever which is pivotally mounted upon a stud 10 projecting from the hopper stand 2. The other arm 11 of the bell crank lever is connected by a pivot 12 to the usual dog 18 which when transfer is called for is adapted to be engaged by the hunter 14 on the lay 15.

The lay is carried by the usual'sword 16 and supports the shuttle box 17 which receives the shuttle 18.

I-Ieretofore an abutment has been carried, either rigidly-or yieldably by the hopper stand .to arrest the filling carriers in tl e proper position in relation to the boxed shuttle and such abutments are generally found to be effective when the usual bobbins are employed, unless, as is sometimes the case, the bobbin is slightly shorter than the standard size to which the loom is adapted.

In looms however in which bobbins having slotted barrels are used it is found that the bobbin is rotated slightly by the engagement of the transfer arm and the guiding means so that when it reaches the shuttle the slabbed faces are not properly positioned in respect to the shuttle jaws.

In the construction illustrated a movable guiding means is interposed between the hopper and the boxed shuttle which is adapted to position and guide the bobbin or filling carrier almost directly into the'shuttle jaws, being so constructed as to hold the bobbin against rotation until it is thrust into the shuttle. In order to provide for the proper cooperation between the transfer arm and the shuttle as it is brought into transfer position by the lay, means are provided for moving the guide concurrently with the movement of the lay and so that the cooperation of these parts will be properly timed to effect the result above described.

The preferred form of guide which is illustrated in the accompanying drawings comprises a plate 20 having preferably integral extensions 21, 22 slidably mounted upon ledges 23, 24: carried by the hopper stand, the extensions 21, 22 being desirably pro vided with slots 25 to receive screws 26 seated in the extensions 23, 24: and having enlarged heads to retain the plate 20 slidably in position upon its supports. The central portion of the plate 20 is provided with a downwardly extending boss 27 which has an offset portion 28.

The boss and the offset portions are vertically apertured to receive the butt of the bobbin, the ofiset portion having a recess 29 its with parallel walls adapted to engage the slabbed faces of the bobbin butts and the force the bobbin longitudinally into its place in the guide, if by chance it is slightly out of alinement.

The member 81 is preferably held in forward position by a spring 86 which at one end bears against the said plate and at the other end bears against the side of the ledge 28 of the hopper stand.

In order to limit the forward movement of the plate 81 it is desirably provided with an integral downwardly extending tail 88 upon the opposite side of its pivot, said tail engaging the side of a web 89 which extends upwardly from the guide 20 between the cars 88, 84.

By this construction the spring 86 is adapted to perform the double function of maintaining the yielding member 81 normally in advanced position and also of restoring the guide as a whole to its normal position when permitted to return after transfer has been effected.

As the transfer from the hopper to the shuttle must be effected with exceeding rapidity it is found necessary, or at least desirable, that the guide move concurrently with the lay as the latter approaches transfer position. In the present case such movement is provided by causing the transfer arm to move the guide simultaneously with the transfer head.

A preferred embodiment for accomplishing this purpose comprises a link 40 pivotally connected to a stud 41 on the arm 11 of the transferrer, said link 40 having at its opposite end a slot 42 adapted to receive a stud 48 extending laterally from an arm 44 on the extension 21. When transfer is called for in the operation of the loom the dog 18 is raised into the path of the hunter 14 in the usual way, whereupon the further movement of the lay rocks the transfer arm upon its pivot so that the head 8 engages the butt of the bobbin and thrusts the same first into the guide and upon further movement into the jaws of the shuttle in the following manner.

The pin and slot connection between the link 40 and the guide 20 provides for an.

initial movement of the transferrer so that the head 8 may engage the butt of the bobbin and thrust the same into the aperture of the guide 20. At this time the stud 48 will engage the outer end of the slot 42 and further movement of the transfer arm will cause the movement of the guide in the same direction concurrently with the movement of the lay so that as the head 8 of the transferrer arm descends farther the bobbin will be thrust into the shuttle.

In order to avoid interference between the guide in its movement and the descending transfer arm the latter iscut away at 9 sufficiently to permit the guide to reach the limit of its throw without striking the end of the transfer arm.

After transfer has been effected and the lay moves in the opposite direction the spring 86 forces the guide into its normal position in the manner above described.

While I have illustrated herein a preferred embodiment of my invention various modifications thereof may be made within the scope and spirit of the invention as covered by the following claims.
